FAUCET.

SPECIFICATION formingpart of Letters Patent No. 288,865, dated November 20, 1883.

Application filed August 10, 1883. (Xo model.)

iro @ZZ whom t may concern..-

Be it known that We, J OHN R. RUEOKERT and ROBERT A. HALL, both of the city of Baltimore and State of Maryland, have invented certain Improvements in Faucets, of which the following is a specification.

To fully understand the nature of our im* provement it must be remembered that after turning the key of a faucet to stop the iow of liquid the portion of the barrel between the key and the outlet or discharge end retains its contents for a considerable period of time, or until air has an Opportunity to pass to the head of the suspended column of liquid and counterbalance the pressure of the atmosphere acting on the other end of the column.

The object of this invention is therefore to Overcome this difficulty by constructing a faucet with means to admit air rapidly to the upper end ofthe suspended column upon the closing of the key, as will hereinafter fully appear.

In the accompanying drawings, forming a part hereof, Figure I is a longitudinal section .of the improved faucet closed. Fig. II is a Opening in the key is represented by b, and c is an air-channel leading from the upper part of the key to a crossopening, d, in the same.

The opening d is at a right angle with the liquid-discharge opening t, and is located some distance above it. The portion a of the barrel is enlarged at its inner end to bring it in communication with the cross air-opening d in the key B.

By referring to Figs. I and II it will be seen that air passing through the aperture c communicates with the interior of the portion a of the barrel in either position that the key may be placed to out off the flow of liquid. In Fig. III the key is in such position as to allow a vdischarge of liquid, the opening b being in a line with and forming a portion of the passage in the barrel. "When the faucet is open, as shown in' Fig. III, both ends of the cross air-opening d are stopped.

vVe are aware that faucets having their discharge through the lower end of the key have been constructed so as to admit air to the interior of the key, and this construction we disclaim; but

We claim as our invention-A In afaucet, thekey thereof closed at its lower end and provided with a controllable opening to admit air, when the key is closed, to the portion of the barrel between the key and the discharge end of the barrelsubstantially as and for the purpose specilied.
